Abstract

Summary: RAFT is applied to the dendronized macromonomers of the first and second generation, 1 and 2, respectively. Good results are obtained in the presence of AIBN as radical initiator, with compound 6 as mediator and at mediator to monomer ratios of 2:200 for monomer 1 ($\overline M _{\rm n}$ = 320 000, PDI = 1.24) and monomer 2 ($\overline M _{\rm n}$ = 178 000, PDI = 1.20). The common characteristics of a controlled polymerization are reasonably met. The more sterically demanding G2 monomer 2 requires higher polymerization temperatures.

## Abstract A novel process to produce homo‐ and copolymers by RAFT polymerization in emulsion is presented. It is known that RAFT‐controlled radical polymerization can be conducted in emulsion polymerization without disturbing the radical segregation characteristic of this process, thus leading to
